Chris Peterson 06a7d5c549 Bug 1473217 - Part 2: dom: Fix misc-unused-raii warnings. r=baku
nsPrintfCString creates a formatted string, but doesn't print it.

ExtractOriginData is called for its constructor's scope and origin out parameters. This ExtractOriginData object doesn't really need a name because it is unused after we have scope and origin,  but this change makes clang-tidy happy and makes the code clear that ExtractOriginData is an object and not a funcion being called.
